RIVETER.

Specification of Letters Patent.

Patented Jan. 17, 1922.

Application filed February 13, 1919. Serial No. 276,776.

To all 107mm it may concern.'

Be it known that I, IVILLIAM P. KnAUsn, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Riveters, of which the following is a specification.

This invention relates to improvements in riveters, and has for its object to provide a new and improved form of riveter construction, which may be applied to yoke and lever compression type riveters, of the kind known in the trade as Hanna riveters, to enable them to handle such work as riveting channel and I-beams.

I-Iitherto special devices and `machines have been required to handle the type of work mentioned, where projecting flanges render it impossible for the riveting dies or stakes to reach the points of riveting, especially where small work is being handled.

My invention provides a construction which will overcome thedeiciency of ordinaryriveting machines and enable it to handle this type of work. This and other objects of theA invention will be more fully set forth and described in the following specification, taken in connection with the accompanying drawings, in which- Figure 1 is a side elevation of a Hanna type of riveter portions being broken away for clearness, with my invention applied thereto;

Fig. 2 is a vertical section through portions of the construction shown in Fig. 1, showing a detail of the application of my invention and means for securing the lower die or stake in place;

.Fig 2a is a view similar to Fig. 2, showing the means for compensating for wear of the lower die;

Fig. 3 is a plan view of the construction shown in Fig. 2;

Fig. 4A is a transverse cross section, taken on the line 4 4 of Fig. 2a, the locking pin being shown in elevation;

Fig. 5 is a front elevation of my machine, showing a modiied arrangement of the lower stake;

lig. 6 is a side elevation of the same; an

Fig. 7 is a side elevation of a compression lever type of riveter, showingY my invention applied thereto, portions thereof being shown in section.

Like numerals refer to like elements throughout the drawings, in which 10 designates generally the yoke of a riveter of the ld anna type, the operation and general construction of which form no part of my present invention, and which needs no description herein. Extending through the upper jaw X of the yoke is the usual movable or reciprocable die screw 11, carrying the upper die 12.. In the usual construction of this type of riveter a co-acting stationary vertical die is located in the lower stake or jaw I of the yoke beneath the moving die; but I replace this in my invention by a lower auxiliary stake casing, generally indicated by the numeral 13, consisting of a base plate 13, secured by bolts 13", or the like, to the lower stake Y, and in which is fitted the lower auxiliary stake 14 constructed with the rivet cup 14d. In the form shown in Figs. l, 2, and 4 the lower auxiliary stake 14 is provided with a flattened surface 14, with which co-acts the flattened surface 15a of a locking pin 15, which extends transversely through cross apertures in the casing 13, as shown in Figs. 2, 3, and 4, respectively. The locking bolt 15 is provided with the head 15", as shown in Fig. 4, which, contacting with the lower auxiliary stake 14, properly seats the locking pin in assembled relation to same, the flattened surfaces of both members being in contact, as shown in Fig. 2, for example.

In the form of lower auxiliary stake shown in the drawings, Figs. 1, 2, 2a, 3 and 4, in order to provide a thrust surface for the lower end of the same, a block 16 is provided, of contour to fit the bore of the casing 13, and having one face inclined so as to lie upon the upper surface of the lower stake Y of the yoke, and another to lie in a plane at right angles to the axis of the bore of the casing 13, so that the base of the lower auxiliary stake will contact therewith.

At its upper end the lower auxiliary stake 14 is cut away, as indicated by numeral 14", and cut olf to form the top face 14, in which is provided the die cup 14".

In my construction, as shown, it will be apparent that the lower auxiliary stake 14, by virtue of its inclination, will fit between the flanges of a channel beam, such as indicatedby letter A, see Figs. 1 and 2, b eneath the upper flange thereof, to permit riveti of a fiat, angle, or other strip thereto, whic function is not possible where vertical stakes are used, as would be obvious from an examination of the drawings. Otherwise, in machines of this type, the only kind of channel or I-beam structures which may be handled are those in which the distance betweenthe flanges is greater than the distance from the top of the lower vertical riveter die to the bottom of the lower stake of the riveter.

As the lower auxiliary stake wears down, provision may be made for such wearpby ren'ioving it and inserting washers or shims 16 lbetween the base of the same and the top of the block 16, and the upper end may be dressed ott, as indicated by the dotted lines in Fig. 2, to bring the rivet or die cup or depression into proper alinement with the upper or movable die, so that the lite of the lower auxiliary stake can be prolonged.

In Figs. 5 and 6 I have shown a different form of construction, in which the riveter.

10 is made more compact, and especially constructed to utilize the inclined lower auxiliary stake or jaw construction. In this embodiment the riveter yoke is provided withy the inclined lower stake or jaw 20, centrally bored as indicated in dotted lines in Fig.A 6, the socket being designated by numeral 20a. rlhe bore 20a is shouldered to provide a thrust shoulder for the shoulder 21a of the lower auxiliary stake 21, which is reduced in diameter below such shoulder 21a, as indicated by numeral 2lb. A locking pin 22 is provided, the same having a flattened surface to co-act with the iattened surface 21c of the lower auxiliary stake 21,V

as in the construction shown in Figs. 2 and 4, the main difference being that a set screw 23, extending throughV a suitable threaded aperture Ain the lower stake 20, contacts with -the locking pin 22 to maintain the same in "2lb ofthe lower auxiliary stake 21, between the shoulder 21"L of the lower auxiliary stake 21 and the corresponding shoulder of the bore 20a.

Theconstruction just described is desirable when constructing a riveter especially for channelled work, whereas that shownin Figs. 14C permits the adaptationV of theV old style verticalv die machines to handleV the channelled form of work.

"In Fig. 7 I have shown my invention as lapplied to another type'of riveter,.known as the compression lever type,vwhe'refthere Y V-is provided a xed lower lstake or jaw 3() and ainovable upper jaw 31, each bf said jaws being provided with bores 32, similar to that shown and described in connection with F-ig. 6, the auxiliaryV stakes 21 being the same as in Fig. 6. In this form of machine I provide two inclined dies 21, one of these dies corresponding to the auxiliary stake of the previously described` form, whereby the riveting of one .channel member to another may be accomplished, as shown in Fig. 7, where two channel beams B and C are shown as being riveted together, thus illustrating the advantage of the construction.

It will be seen from an examination of the structure shown in Fig. 7, that both auxiliary stake members in this embodiment are arranged at an angle with respect to both the horizontal and vertical, and that the included angle therebetween is less than a'straight angle, or 1800. YIn other words, both are normally arranged at an angle with respect to the operative axis, that is, in the embodiment shown, the. axis of the rivet being riveted.

It will be obvious that my invention is susceptible kto modifications and improvements, and I do not wish to be restricted thereto, except as defined in the appended cIaims.
